Fig. 20a — L-system tree
VDC College as a growing tree — after Prusinkiewicz et al., “Modeling plant development with L-systems”
WHAT THE TREE SHOWS
Root — Jointer (the junction the college grows from)
Trunk — VDC College
Branch — Course + batch year (BCA 2025, B.Com 2026 …)
Leaf — Student of that batch
6 courses · batches 2024–2027
Branches per fork — add / removek = 6

L-system
Axiom: A(0)
A(d): d < T → I(1.5·l) A(d+1) (trunk)
A(d): T ≤ d < D → ( I(l) [ /(φ) &(α) A(d+1) ] )ᵏ K
A(d): d = D → I(l) K
I(s) → F(s) (turtle, 3 sub-segments)
K → leaf
branch: smooth arc — bend H around
per-branch axis N̂ (β ≈ 0.5–1.6°)
width: d₀^η = Σ dᵢ^η (pipe model)
tropism: bend H toward E = out + up·b
angle = e·|E×H|
